Since former Google executive Mayer became chief at Yahoo, the company has racked up a series of acquisitions including startups Alike, Stamped, Snip.it and a Summly application built by a British teen.

Yahoo recently bought PlayerScale, a startup that powers games played on smartphones, tablets, consoles or personal computers.

Yahoo is reported to be eyeing online video website Hulu after its bid to buy a majority stake in France-based Dailymotion was derailed in May.

Mayer's plan for reviving the fortunes of the faded Internet pioneer includes making priorities of mobile devices, video, personalized digital content, and elevating the company's popularity outside the United States.
